It's not clear, however, that Obama is in any real danger sharing a ballot with this initiative in Colorado. For all the disappointment in the marijuana reform community with Obama, it's hard to imagine pro-marijuana voters breaking for Mitt Romney either — who scolded a reporter for even asking about pot.

The real alternative for pro-marijuana reform voters is Gary Johnson — the Republican-turned-libertarian candidate and admitted medical marijuana user. But a recent New Mexico poll showed that when Johnson polls strong, he mostly hurts Romney. The latest New Mexico numbers (Johnson's home state) show the former two-term governor at 12 percent, with Romney trailing Obama 35 to 48 percent.
